Product Description

Shandong Leader Machinery Co.,Ltd. cold and hot amphibious screw oil press machine is a new research improvement product.Palm Fruit Processing Line is for oil extraction from oil-bearing materials,such as rapeseed,peanut,tea seed,soybean, sunflower seed,shea butter,palm kernel and so on.Equipped with micro-electrical control,infrared heating and filtration system,Dinter sunflowers oil press equipments/extractor can press oil through cold press and hot press. Pour raw material to the machine,Shandong Leader Machinery Co.,Ltd. can get pure oil which can be eaten directly.Dinter sunflowers oil press equipments/extractor is very suitable for individual users.

The specificaitons of Dinter sunflowers oil press equipments/extractor:(1).Cleaning: Our vibration screen and destoner will Remove the raw material peanut in various impurities, such as: iron, stones, clump, such as the plant leaf, clean up after the raw material peanut impurity content should not exceed 0.2%.(2).Crushing: Oil seed is crushed into 6-8 pieces. In order to meet the requirements of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.(3). Softening: The purpose of softening is to adjust the moisture and temperature of oil, and make it soft.(4).Flaking process: Rolling raw material into flakes, and the purpose is to increae surface area, destroy the peanut cell tissue, shorten the way of oil out from cake.(5).Drying: Adjust moisture of rice bran to meet the requirement of going to extraction process. (6).Cooking process: use steam cooking, inject direct steam and cook the flakes to meet the requirement of oil press.

Product Description

Dinter sunflowers oil press equipments/extractor processes:

1. cleaning process

Use magnetic selector to remove metal impurities and other impurities with cleaning screen, specific gravity stoner and dust remover. If itâs sunflower seeds for oil usage, shelling is not required; if for edible type, shelling is required.

2. crushing process

Use crusher to crush sunflower seeds into pieces to get smaller particle size for flaking.

3. flaking process

Rolling sunflower seeds particles into flakes with flaking roll to break its cellular structure and then separate oil easier when extracting.

4. cooking process

By adjusting sunflower seeds flakes to suitable moisture and temperature to break internal structure of sunflower seeds so as to separate oil from oil seeds .

5. Pre-pressing process

Use oil press to press part of oil firstly to decrease oil content prior to extraction.

Dinter sunflowers oil press equipments/extractor Extraction Process:

1) continuously pumping solvent to the rotary-type extractor

2) prepressed cake is soaked and sprayed with solvent to dissolve the oil fat. after this step, you will get wet meal and mixed oil

3) DTDC is used to separate the solvent from the wet meal

4) pumping the miscella( oil with solvent ) into the 1st miscella tank and then adding 10 percent saline water, with which the phospholipid and impurities will react to reach the goal of purifying

5) the purified miscella will be pumped into the second miscella tank

6) the remaining solvent in miscella will be removed using the method of stripping and will be discharged to condenser for recycling

7) condensers are used for the cooling of the solvent gas separated from the wet meal and for recycling miscella

Dinter sunflowers oil press equipments/extractor Refining:

1) Degumming: degumming process refers to the situation that dissolved phospholipid and viscose material are to be removed from the oil under high or low temperature by making them soluble in the water. Using phosphoric acid can facilitate the degumming process. Soluble phospholipid can be removed with the added water and nonsoluble phosphoric acid is very hard to remove, requiring the handling of concentrated acid to be removed. The choice of water and acid used in the degumming depends on the oil type.

2) Neutralization: NaOH is added to the degummed oil to make free fatty acid, phospholipid, and most of the pigment content become saponated subtance for the purpose of deacidification. generally, the neutralization process includes three steps: neutral soap separation, neutral soap washing and vacuum drying.

3) Dewaxing and winterlization: the purpose of it is to remove fog shaped solid substances existing in the oil of freezing temperature. those solid substances are made of saturated triacylalycero or waxiness.

4) Decoloration: decoloration is to remove most of the pigment substances in the oil including colloid,trace amount of saponificaton and other impurities.

5) Deodorization: deodorization is the final step of the oil refining. this process uses steam stripping to remove smelly substances under the condition of vacuum and high temperature.
